The Relationship

The relationship between parental mass and female reproductive output, as well as offspring quality, was studied in the red cherry shrimp (Neocaridina davidi (Bouvier, 1904)) under controlled laboratory conditions. Adult males and females of the same age were paired combining different shrimp masses. The number of hatched juveniles from large females was higher than that from small ones, but no influence of paternal mass was detected on this variable. Both the mass of newly hatched juveniles and their growth increment during a 60-day period were similar for all parental masses. Shrimps reached sexual maturity at the end of the growth period in all treatments, and their biochemical reserves (glycogen, lipid, and protein concentrations) were not associated with maternal and paternal masses. However, lipid concentration was higher in female offspring than in male offspring. The present results show that, unlike maternal mass, paternal mass had no effect on female reproductive output and offspring quality, suggesting that the contribution of males to offspring development was adequate regardless of male size.

Energetic Reserves

Forest fragmentation creates edge habitat that attracts nest predators that lower reproductive success and force birds to renest. To determine if predation-induced renesting causes a decline in condition of females and reduces productivity and offspring quality, I measured maternal condition and reproductive output of Indigo Buntings breeding in a fragmented and a contiguously forested landscape in Missouri. Renesting females had lower body condition than those that nested once successfully. As maternal condition declined with nesting attempt, stress hormone levels increased, suggesting poor-conditioned females lack the energetic reserves to meet increased demands. Additionally, females in poor condition produced small clutches and poor-conditioned nestlings. A higher proportion of nests containing all-female offspring indicates a bias in production of the smaller, less profitable sex in the fragmented landscape. These results suggest that increased reproductive effort associated with renesting imposes costs to breeding females and decreases their ability to invest in high quality offspring.

Abstract The protracted spawning period of broadcast-spawning marine fishes has potential to generate considerable variability in metrics of individual reproductive output. We undertook a temporally detailed genetic study of larvae produced by Atlantic cod (Gadus morhua) from two spatially proximate populations spawning under controlled semi-natural conditions over 94 days. Based on daily samples of larvae (n = 4489 in total), we document fine-scaled temporal changes in, and correlates of, offspring phenotype and reproductive output (egg batches produced or fertilized). Larval length and standardized yolk-sac volume declined 11 and 49% over the spawning period, respectively. The adaptive significance of these trends is unclear. Longer, heavier females produced longer, better-provisioned larvae. Body size affected the number of egg batches to which an individual contributed genetically but not spawning duration. Males contributed gametes to a greater number of egg batches (19.5 vs. 9.2), and spawned over a longer period of time (48.9 vs. 30.8 days), than females. After accounting for body size and condition, egg batch number and spawning duration differed between adjacent populations separated by < 10 km. Our work highlights the need to understand the environmental and adaptive causes of temporal variability in offspring quality and its consequences to individual fitness and per capita population growth in batch-spawning fishes.

Spawning Periods

Reproductive allocation in the multiple-spawning pumpkinseed (Lepomis gibbosus) was estimated in two non-native populations in southern France and one native Canadian population with experiments conducted in artificial enclosures, supplemented with data collected from wild populations. Reproductive allocation, estimated as the sum of mass lost over weeks when fish spawned, averaged 24 and 27% of prespawning body mass in the two French populations and 11.5% in the Canadian population. Estimates generated from a bioenergetics model and from batch fecundity in field-caught females gave similar results. Females from the French populations averaged 2.9 and 3.1 spawning periods, whereas the Ontario females averaged 2.1 spawning periods over a shorter spawning season. Body size was weakly correlated with reproductive allocation in one French and one Canadian population. The level of reproductive allocation in pumpkinseeds is considerably lower than that estimated in other multiple-spawning fishes. We suggest that multiple spawning can evolve solely to allocate the production of young in a variable environment and not necessarily to increase the total reproductive output of the female.
